Facility Overvoltage Protection
The robot must be protected from excessive overvoltages and voltage spikes. If the
country of installation requires a CE-certified installation or compliance with
IEC 1131-2,
the following information may be helpful.
IEC 1131-2 requires that the installation must
ensure that Category II overvoltages (i.e., line spikes not directly due to lightning strikes)
are not exceeded. Transient overvoltages at the point of connection to the power source
shall be controlled not to exceed overvoltage Category II, i.e., not higher than the impulse
voltage corresponding to the rated voltage for the basic insulation. The user-supplied
equipment or transient suppressor shall be capable of absorbing the energy in the
transient.
In the industrial environment, non-periodic overvoltage peaks may appear on mains
power supply lines as a result of power interruptions to high-energy equipment (such as a
blown fuse on one branch in a 3-phase system). This will cause high current pulses at
relatively low voltage levels. Take the necessary steps to prevent damage to the robot
system (for example, by interposing a transformer). See
IEC 1131-4 for additional
information.

Figure 4-4. Typical AC Power Installation with Single-Phase Supply
DANGER: AC power installation must be performed by a
skilled and instructed person - see Section 2.12 on page 32.
During installation, unauthorized third parties must be
prevented, through the use of fail-safe lockout measures,
from turning on power.
